Confirm whether to be set at the high process of cleaning of heating, carry out classification processing.
Step S108
When being set at that heating is high cleans process, be according to the cloth amount control output of detected washings in the step 104.That is, the cloth amount is many more, and output is just many more.Specifically, the water yield (L) in supply is about 1.5 times the moment of cloth amount (kg), just stop supplies washing agent water.When supply water finishing, water just is in the hold concurrently state of bottom of exhaust outlet 6b and urceolus 6 of bellows 29 and internal pipeline 30, bellows 39, draining that is full of.
The part of powder detergent is dissolved because of the stirring action of washing agent water, and remaining washing agent remains on the bottom surface of urceolus 6 with the state of particle (dissolving).At this moment, produced approximately high 3～5 times high concentration detergent liquid of concentration in the bottom of urceolus 6.At this moment, normal concentration is the powder detergent amount 20 gram/washing water yields 30 liters.
Step S109
Through running washings circulating pump 32, deliver to the washing agent liquid of the high detergent concentration that accumulates in urceolus 6 bottoms in the watering mouth 25, trickle down again and to washings, it is soaked into.At this moment, implement the dehydration drive pattern, washing and dewatering tube 2 is rotated.Perhaps, implement the washing drive pattern, make pulsation impeller 4 carry out positive and negative rotation repeatedly.Through this process, owing to changed the relative position of watering mouth 25 with washings, thereby high concentration detergent liquid is sprinkled upon on the washings equably.
Owing in step S108, controlled the detergent use water yield (controlling to the water yield that washings can absorb) according to the cloth amount of washings; Trickle down all washings absorptions of washings on washings; Thereby the washings that in exhaust outlet 6b, bellows 39 are held concurrently in the bottom of urceolus 6 and draining, almost do not accumulate; Because not from watering mouthful 25 discharge washings, so the washings circulating pump 32 that shuts down.Like this, just can form reliably from draining and hold concurrently exhaust outlet 6b through electric blowing machine 43, ptc heater 46 arrives the air circulation channel of puff prot 24.
In addition,,, turn back to the bottom of urceolus 6, begin to accumulate in the bellows 39, reduced the area of the air flow channel of bellows 39 owing to gravity breaks away from washings when after a period of time, absorbing a part of washings in washings through process.When the air bellows 39 I reduced flow area, in step S111, when the hot air blowing, the bellows 39 will increase the flow rate of the air, accumulated in the bellows 39 will be from the surface of the wash water waves, generated detergent bubbles.This foam is just upwards blown on the flocking filter 42 with air, and sticks on the flocking filter 42, and the pressure loss that will produce flocking filter 42 increases and because of problems such as the adhesion of washing agent are mouldy.For this reason, can let washings circulating pump 32 carry out intermittent running, regularly eliminating accumulates in the washings in the bellows 39.
Step S110
Confirmed not have water remain in bellows 39, draining hold concurrently exhaust outlet 6b, urceolus 6 bottom (that is, air circulation duct is unimpeded) afterwards, just carry out classification processing.Whether confirm to have residual water can detect apart from the output signal of the level sensor (not shown) of the water level of bellows 39 bottoms through observation carries out.
At input washings is not dry cloth, but when containing the washings of water, washings will be because of the moisture weight that become, so detected cloth amount is just more than the cloth amount of reality in step S104, the water yield of supply is just too many.Like this, in order not allow many absorption and washing of washings water, even after step 109; Also can be at the hold concurrently remaining washings in bottom of exhaust outlet 6b, urceolus 6 of bellows 39 and draining; Make air circulation duct be in blocked state, owing to can not carry out hot air circulation, thereby to jump to next procedure S111.
Step S111
The motion class of the washings of this moment is similar to the motion of the cloth of drying process, and washings is beated to the top by means of the rotation of pulsation impeller 4, between washings, produces the space, and hot blast just gets in these spaces.Like this, hot blast not only can blow to the outer surface of washings, can also blow to the inside of washings, and the whole temperature of washings is raise.If do not need this effect, the impeller 4 that also can replace with common stirring vane pulsing constitutes the scrubbing-and-drying unit structure.In addition, even aforesaid hot blast wind pushing mechanism to washings supply hot blast is set, also can improve clean effect in the washing machine that does not carry out drying process.In this case, can reduce the capacity of ptc heater.In the scrubbing-and-drying unit of present embodiment, two ptc heaters are housed, though in drying process, produce hot blast by two ptc heaters; But; Because in the hot air circulation before the washing work, washings need be as drying process high temperature, so only use a ptc heater.Therefore, if washing machine has the hot air circulation function, as long as of having in two ptc heaters that scrubbing-and-drying unit has is just passable.
When the temperature of washings rose, the temperature of the high concentration detergent liquid that is contained in the washings also rose.So, the chemistry of high concentration detergent liquid is cleaned ability, will further improve owing to temperature rises the effect that produced, just can make at an easy rate attached to the dirt on the washings to come off.Lipase that is contained in the powder detergent (fats catabolic enzyme) and protease enzymes such as (protein decomposition enzymes) have and can bring into play its active temperature, in the enzyme that washing agent contained of washing usefulness, are about 30～50 ℃.Therefore, in this step, rise in so far through the temperature that makes washings, enzyme just can play to greatest extent and acts on, and can all divide the dirt of fats and protein-based dirt and take off, thereby can it come off from washings.But, because kinds of protein is different, what have has just solidified at 43 ℃, becomes the material that is difficult to come off on the contrary, so, preferably be controlled at the temperature of washings and the highlyest be no more than 40 ℃.
In this step, because only high concentration detergent liquid heating, be fed to washings in the washing and dewatering tube 2 with handle and heat all and compare being contained in washings and the washings, can bring into play the effect of washing agent to greatest extent with the small electric power consumption.
Step S112
Under the situation of the high clean process of heating, open washing agent water supply electromagnetic valve 48a again, the powder detergent input space 13b that drops into device 13 to washing agent supplies water.In addition, under the high situation about cleaning beyond the process of heating, begin to proceed to supply water from step S106.
Step S113
, water supply just stops to supply water when reaching the water level of detergent dissolution.In the present embodiment, be set at about 10 liters to the washing agent output, and irrelevant with detergent amount (cloth amount).This water yield is to set like this; Promptly; Make when washing and dewatering tube 2 is rotated that for agitator treating water and the washing agent of dehydration tube 2 bottoms after supplying water of holding concurrently, its water yield is enough; And the water surface also is lower than the height of the lower surface of pulsation impeller 4.
Step S114
Through making washing and dewatering tube 2 and pulsation impeller 4 together to same direction slow rotation (about 70 rev/mins); Detergent dissolution water in this washing and dewatering tube 2 and the powder detergent that remains in urceolus 6 bottoms are stirred; Make detergent dissolution, to form the washing agent liquid of high detergent concentration.It is just enough that the time of detergent dissolution has 1 minute.Even, 90% dissolution rate is arranged also at low temperature (low water temperature), not under the condition of diffluent powder detergent.
Step S115
Carry out preposition washing.This preposition washing is to let washing and dewatering tube 2 be under the static state; Make pulsation impeller 4 do positive and negative rotation, carry out intermittence and stir, in the forward and backward process of pulsation impeller 4; By means of letting 32 runnings of washings circulating pump; Deliver to delivery port 26 to the washings of urceolus 6 bottoms, unrestrained again to washings, carry out circulation intermittently.Pulsation impeller 4 and washings circulating pump 32 stop during; Then with reference to the detection signal of level detection sensor 28; Open washing agent water supply electromagnetic valve 48a and washing water supply electromagnetic valve 48c, replenish the running of supplying water, let water level be no more than designated water level h1, h2 through carrying out three times repeatedly; Washings is dispersed on the pulsation impeller 4, lets it soak into washings.
The velocity of rotation of the pulsation impeller 4 of this preposition washing is that middling speed is rotated (approximately 100rpm), and the rotation time limit (just changeing time/dwell time/reversing time) of rotating for the first time approximately is to rotate 0.6 second, stops 0.8 second, about so repeatedly 30 seconds; The rotation time limit (just changeing time/dwell time/reversing time) of rotating for the second time approximately is to rotate 0.6 second, stops 0.8 second, about so repeatedly 1 minute and 30 seconds; The rotation time limit of rotating for the third time (just changeing time/dwell time/reversing time) approximately is to rotate 2 seconds, stops about 1 second, about so repeatedly 3 minutes.
In first time during forward and backward, detergent concentration is approximately 7 times washings and trickles down on washings, is impregnated into the inside of these washings.Because the effect of the washing agent liquid of this high detergent concentration, dirt has all broken away from washings, thereby can obtain very high cleaning strength.Through the water that replenishes the supply times without number, the detergent concentration of trickling down in the washing agent liquid on washings just descends, and in preposition washing ending phase, then is about the twice of normal concentration.
In addition, in preposition washing, why get the time set of the rotating first time the shortest; Be in order to prevent the generation of scenario: promptly, washings only contains the water when supplying water in advance at the beginning, and dry part is a lot; When spilling when letting washings circulate; Just washings absorbs immediately, and the washings of urceolus 6 inner bottom parts are reduced in the short time significantly, causes the circulation of washings not carry out.In addition, the rotation time limit of rotating is because spilling the washings that get off can soak into washings with very high efficient at preceding half section shorter of preposition washing, and is formal because this situation makes whole washings can in the very short time, all soak into washings.Then, the rotating for the third time after washings perfuse whole washings basically through carrying out the long period with the long rotation time limit, just can improve its cleaning strength expeditiously.
Step S116
Basically wash.In this basic washing, at first, use with above-mentioned same method and carry out the detection of cloth amount, the wash time that sets is revised setting.Then; Be under the static state at washing and dewatering tube 2; Let pulsation impeller 4 carry out positive and negative rotation on one side; Let washings circulating pump 32 turn round on one side, let the washings that accumulate in urceolus 6 bottoms trickle down about two minutes pressurization wash agitation that the washings on washings circulate from watering mouth 25; , stop the running of washings circulating pump 32, under the state that the washings circulation stops, making pulsation impeller 4 carry out about 1 minute positive and negative rotation, to untie the stirring of cloth repeatedly thereafter; At last, stop the running of washings circulating pump 32, under the state that stops the washings circulation, carry out about 1 minute homogenising that lets pulsation impeller 4 do positive and negative rotation and stir, thereby finish basic wash time.The velocity of rotation of the forward and backward of the pulsation impeller 4 in this basic washing; When the pressurization wash agitation, be rotation (about 130rpm) at a high speed; When the stirring of untiing cloth middling speed rotation (about 100rpm), the rotation time limit of rotating (just changeing time/dwell time/reversing time), limit for length in the time of letting rotation time limit of the stirring of untiing cloth than the rotation of the wash agitation of pressurizeing; For example; The rotation time limit of pressurization wash agitation is approximately 2.5 seconds, is approximately 3.0 seconds and untie the rotation time limit that cloth stirs, and stopping the time limit all approximately is 1 second.
Step S117
Carry out the trickle rinsing.In this trickle rinse cycle, at first carry out the draining of washings and the washings that contained in the washings are carried out centrifugal dehydration.The draining of washings is through opening drain solenoid valve 31, and washings in the urceolus 6 are flowed into through bellows 29, internal pipeline 30, drain solenoid valve 31 and get rid of the externally drained flexible pipe 33 from the draining exhaust outlet 6b that holds concurrently.In addition, centrifugal dehydration is through control washing dehydration drive unit 8, and washing and dewatering tube 2 is implemented to a direction high-speed rotation with pulsation impeller 4.When washings dewater, washing and dewatering tube 2 and the velocity of rotation of pulsation impeller 4 be set at after the velocity of rotation (approximately 1000rpm) of the final dewatering stated identical, the time of dehydration running approximately is 2 minutes and 30 seconds, to realize high dehydration rate (about 60%).Then, carry out the rinsing of cylindric washer rotation trickle.Washings through after the dehydration running is in the state that is attached on washing and dewatering tube 2 inwalls.By means of the inwall that lets delivery port 26a towards washing and dewatering tube 2, just can drench on the washings that is attached under the washing and dewatering tube 2 inwall states with the sufficient washings of mode handle of trickle.The trickle rinsing of this cylindric washer rotation; Be under drain solenoid valve 31 closing state, Yi Bian make washing and dewatering tube 2 with pulsation impeller 4 to a direction slow rotation (35～40rmp), open on one side and wash water supply electromagnetic valve 48c; Through letting running water; The water for bathing suction pump 48d that perhaps turns round, the remaining hot water of will having a bath ejects, from the unrestrained washings to the pulsation impeller 4 of delivery port 26a.The rinsing water yield of this moment approximately is 9 liters.In addition, in the trickle rinsing that this cylindric washer rotates, as required, can also make 32 runnings of washings circulating pump, the washings that accumulate in outer bucket 6 bottoms are sprayed out from watering mouth 25, circulate.At this moment, because delivery port 26a is towards the inwall at the depth place of washing and dewatering tube 2, so can spray uninterruptedly with the washings that spray out from watering mouthfuls 25 from the depth of inner cap 23.
Step S118
Carry out the water storage rinsing first time.In current water storage rinsing; At first, open drain solenoid valve 31, after discharging the washings of the cylindric washer rotation trickle rinsing that accumulates in urceolus 6 bottoms; Washing and dewatering tube 2 is rotated to a direction with pulsation impeller 4, the washings that washings contained are carried out centrifugal dehydration.When carrying out the dehydration of this washings; The velocity of rotation of washing and dewatering tube 2 and pulsation impeller 4; Be set at after state final dewatering the time velocity of rotation (about 1000rpm) identical, carry out about 2 minutes 30 seconds dehydration running, to realize very high dehydration rate (about 60%).
After this, close drain solenoid valve 31, make washing and dewatering tube 2 with pulsation impeller 4; On one side to a direction slow rotation (35～40rpm); Open on one side and clean water supply electromagnetic valve 48c, from delivery port 26a supply running water, and on the unrestrained washings to the pulsation impeller 4.The washings water supply time of this moment is approximately 30 seconds, and output is about 8 liters.
Then, under the state that washing and dewatering tube 2 and pulsation impeller 4 stop operating, the washings that carry out about 30 seconds supply water, so that the water level of urceolus 6 bottoms surpasses designated water level h1, h2.The output of this moment is about 8 liters.
Then; The same with the pressurization wash agitation in the basic washing; Under the static state of washing and dewatering tube 2, let pulsation impeller 4 do positive and negative rotation on one side, Yi Bian let washings circulating pump 32 turn round; Rinsing is stirred in the washings circulation that the washings that accumulate in urceolus 6 bottoms are circulated, and lets it from the unrestrained washings to the pulsation impeller 4 of delivery port 26a.This washings circulation is stirred rinsing and was approximately carried out for 30 seconds.
Then, under the state that the running of rotation and the washings circulating pump 32 of pulsation impeller 4 all stops, detecting the water level of the washings that accumulate in urceolus 6 bottoms on one side, the additional water supply in about 15 seconds is carried out on one side, but water level must not surpass designated water level h1, h2.The additional output of this moment approximately is 4 liters.
Then; Letting under the static state of washing and dewatering tube 2; Make pulsation impeller 4 carry out positive and negative rotation on one side; On one side let washings circulating pump 32 turn round, the washings that accumulate in urceolus 6 bottoms are circulated from the unrestrained washings to the pulsation impeller 4 of delivery port 26a, stir rinsing to carry out the washings circulation.This washings circulation is stirred rinsing and was approximately carried out 1 minute and 30 seconds.
Then, stopping electric circulating pump 32, stopping under the state of circulation of washings, making pulsation impeller 4 continue to do positive and negative rotation, carrying out homogenising and stir.This homogenising stirs approximately carried out 1 minute.
Step S119
Carry out the water storage rinsing second time.In the water storage rinsing second time; Open auxiliary agent water supply electromagnetic valve 48b; Dropping into space segment 13c through the auxiliary agent that drops into device 13 to washing agent supplies water; the control of the bottom of the inner auxiliary agent importing urceolus 6 of this auxiliary agent input space segment 13c, all the other are all identical with the water storage rinsing first time except additional.At this moment, remain on the wall of auxiliary agent input space segment 13c, do not open auxiliary agent water supply electromagnetic valve 48b continuously, and should carry out open and close times without number for auxiliary agent is difficult to.
Step S120
Carrying out final dewatering handles.Final dewatering is to be fixed on drain solenoid valve 31 under the open mode; Running washing dehydration drive unit 8; Make washing and dewatering tube 2 with pulsation impeller 4, rotates to a direction, washing and dewatering tube 2 interior washings are carried out centrifugal dehydration with the high rotating speed of 1000rpm.The duration of runs of this final dewatering, can be set in and to obtain in the time of desired dehydration rate.
Step S121
Carry out drying.This drying is carried out according to following manner under the state that drain solenoid valve 31 is opened: the same with washing procedure, make under the static state of washing and dewatering tube 2; Through making on one side pulsation impeller 4 do positive and negative rotation, through let be arranged on water-cooled dehumidifying air channel 40 midway electric blowing machine 43 runnings on one side, thereby the interior air of urceolus 6; Hold concurrently exhaust outlet 6b through bellows 39 from draining; Suck in the water-cooled dehumidifying air channel 40, when the rising air channel 40a that sucks water-cooled dehumidifying air channel 40 through this is inner, remove wet plate 41 with the water-cooled that is arranged in the 40a of this rising air channel; With flow through this water-cooled and remove the cooling waters on wet plate 41 surfaces and contact; After supercooling, dehumidifying, capture flocking through flocking filter (not shown) again, again by after ptc heater 46 heating that are arranged in the air heating pipe 44; Send into puff prot 24 through bellows 45, blow in the washing and dewatering tube 2 from this puff prot 24.
Cooling water is to discharge like this: through opening cooling water electromagnetic valve 48e; Manage 41a to water service to cooling water flow out of; Make it flow to water-cooled and remove on the surface of wet plate 41, and get off, wander the cooling water that gets off from water-cooled except that wet plate 41 along the surface current of this water-cooled except that wet plate 41; After hold concurrently through bellows 39, draining exhaust outlet 6b, bellows 29, internal pipeline 30, drain solenoid valve 31, flow to back discharge in the externally drained flexible pipe 33.
The control of this drying is realization in the detection signal that the moisture detection sensor 50 of keeping watch on the air humidity after detecting the water-cooled dehumidifying is exported, and is reduced to specified humidity and just finishes when following.
The circulation of the washings of this electric washer is if let washings circulating pump 32 running continuously constantly in a very long time, because the flocking that is contained in the washings will be trapped in the circulation water channel; Can produce the fault (the narrow phenomenon of water channel) that this circulation water channel stops up, so, (for example exceed schedule time when the time of continuous running; 1 minute) time; Every running interrupted (open and close) that will make washings circulating pump 32 at regular intervals once perhaps is provided with flow sensor in the circulation water channel, keep watch on the flow of recirculated water; Perhaps through keeping watch on from the water level detecting signal of level detection sensor 28 outputs; The slippage (along with the minimizing of flow, slippage also reduces) of urceolus 6 bottom wash water water levels is obtained flow during according to 32 runnings of washings circulating pump; When this flow reduces to setting when following, the running of control washings circulating pump 32 makes its interrupted (open and close).When the running that in the washings circulation, makes washings circulating pump 32 is interrupted, because when breaking off (pass), the washings in the circulation flow backwards; And when continuing (opening), washings drag flow (circulation), so; Circulated washing water flows with the mode of vibration in the circulation water channel, and therefore, a part of flocking that accumulates in the circulation water channel is come by dismission; Flow out together with washings, thereby can prevent the generation of plugging fault.The cycle of the intermittent working of above-mentioned washings circulating pump 32, in the present embodiment, approximately be carry out repeatedly opening for 12 times 2 the second/3 seconds of pass, then, turn back to continuous running again.
Groundwork process with scrubbing-and-drying unit of this structure is such: in washing procedure, the water of being supplied that accumulates in above-mentioned outer tube bottom, its water level remain on and are no more than above-mentioned pulsation impeller upper surface; Perhaps on the water level just over a bit; Through the dissolved powders washing agent, produce the washings of high detergent concentration, Yi Bian the washings of this high detergent concentration are circulated; Be sprinkled upon on the washings; Make the pulsation impeller do positive and negative rotation on one side, act on power repeatedly on the washings washing of pressurizeing towards the top; In rinsing process, the same with washing procedure, the washings of being supplied that accumulate in above-mentioned outer tube bottom; Its water level remains on and is no more than above-mentioned pulsation impeller upper surface, perhaps on the water level just over a bit, Yi Bian washings are circulated; Be sprinkled upon on the washings; Make the pulsation impeller do positive and negative rotation on one side, act on power repeatedly on the washings, carry out the rinsing of extruding the washings that contained in this washings (water that detergent ingredients is arranged) towards the top; Then, in drying process, make the pulsation impeller do positive and negative rotation; The same with washing procedure, on one side washings is stirred, go the air sucking-off in the above-mentioned urceolus on one side; After the water-cooled dehumidifying,, blow to again in the above-mentioned washing and dewatering tube, make washings dry through heating; Therefore, use a spot of washings just can obtain very high clean efficient, in addition, can also carry out high efficiency drying.
In addition, specifically, effect and effect below obtaining.
According to the amount with detergent amount (cloth amount) the detected washings of checkout gear, the water of using the dissolving detergent of corresponding water amount supplies and accumulates in the bottom of urceolus with washing agent, produces the washings of high detergent concentration; Be sprinkled upon this washings on the washings, when soaking into washings, the tube bottom washings that just do not accumulate outside; Formed the air channel of reliable air circulation mechanism, blowing in the washing and dewatering tube, through improving washings and the temperature that is soaked in the high concentration detergent liquid in the washings by the hot blast after the heating of air circulation mechanism; Chemical cleaning strength to high concentration detergent liquid has increased the action of temperature effect, makes dirt break away from washings, then; Supply water, make water accumulate in the bottom of above-mentioned urceolus, and let water level remain on to be no more than the upper surface of above-mentioned pulsation impeller; Through making undissolved powder detergent dissolving, produce the washings of high detergent concentration, Yi Bian let the washings of this high detergent concentration circulate; It is trickled down on washings; Make the pulsation impeller carry out positive and negative rotation on one side, act on power repeatedly on the washings washing of pressurizeing towards the top; So the dirt that from washings, floats up just breaks away from washings, thereby can obtain very high clean efficient.
In addition; Washings making high detergent concentration are trickled down on washings, and soak in the process of washings, by means of inner core and pulsation impeller are rotated to a direction together; Perhaps make the positive and negative rotation of pulsation impeller, just can let the washings of high detergent concentration soak into whole washings equably.
In addition, in hot blast being blown to the inner process of inner core, do positive and negative rotation through making the pulsation impeller; Owing to the rotation of pulsation impeller makes washings beat to the top, between washings, can produce the space, hot blast just gets in these spaces; Like this; Hot blast not only can blow to the outer surface of washings, can also blow to the inside of washings, thereby can improve the whole temperature of washings with very high efficient.
In addition; In blowing to hot blast with air circulation mechanism the inner process of inner core; Through making the washings cycling mechanism do running intermittently, can form the air channel of air circulation mechanism reliably, can be when not reducing the air channel basal area; Obtain enough air circulations, thereby can improve the temperature of washings expeditiously.In addition,, produce foam because of the wind that flows, and foam disperses innerly to air circulation mechanism, perhaps bedew the flocking filter, its pressure loss is increased so just can prevent washing agent liquid because washing agent liquid can not be trapped in the air channel.Also have, because washing agent can be attached on the flocking filter, it is mouldy just to prevent that the flocking filter from producing.
In the above-described embodiments, during hot air circulation before washing procedure, make water level lower (almost being the state that whole washings absorbed), thereby can on exhaust outlet 6b part held concurrently in draining, form and lead to the air channel of rising air channel 40a from urceolus 6 one sides.For this reason, make with washings circulating pump 32 to accumulate in the draining washings circulation on exhaust outlet 6b or the outer tube bottom of holding concurrently, make its washings absorption.Need remain in washings draining hold concurrently exhaust outlet 6b or outside under the situation of tube bottom; Perhaps in the scrubbing-and-drying unit that does not have the washings circulating pump; Can be shown in figure 14; On the mid portion of urceolus short transverse (setting the height that the water level during lower hot air circulation can not had by water logging than water level), be provided with and let communication passage that rising air channel 40a is communicated with urceolus 6 to guarantee the air channel.
